Once you see that nandwrite error above, what you should have done is stopping right there, keep the box running, avoid rebooting the box or power down. And then post here for help. If you reboot, then it is bricked for sure.

How did you create this u-boot.kwb file? download somewhere? or did you compile it yourself and from what source?

„These are not NSA325 mtd layout.”
– yes not really because the root was loaded with a usb stick.

„Once you see that nandwrite error above, what you should have done is stopping right there, keep the box running…..”
At this point, I tried to delete and save the different u-boot and yours a few times and unfortunately I had to turn it off.

„If you reboot, then it is bricked for sure.”
Yes I am sure that we are bricked and for this I need to write the u-boot via JTAG.

Network working.
